Online context switching for real time control applications using reconfigurable fuzzy inference chip

The reconfigurable fuzzy inference chip (RFIC) is a novel concept of a hardware fuzzy inference processor. It supports online realtime context switching. Such a capability is significant, particularly for situations where the application scenarios are expected to change dynamically. Furthermore, the RFIC can be extended to support hardware that reconfigures itself, a notion termed as evolvable fuzzy hardware. We outline in this paper a prototype implementation of the RFIC and demonstrate its capability in handling online realtime context switching for the control of a rotary inverted pendulum. Our results confirm the applicability of the RFIC in supporting the implementation of intrinsic evolvable fuzzy hardware
